mtk_set: Sets Object Attribute Value

It is, essentially, the opposite of the mtk_get primitive. It allows the user to change the value of a MTKObject's attribute, setting it to a specific value.

Usage: mtk_set(tangram2_source_variable, mtk_object_name,
object_attribute [,index_list ] )

where tangram2_source_variable specifies the Tangram-II variable that holds the new value; mtk_object_name is the MTKObject whose attribute will be changed; object_attribute the attribute's name; and [,index_list] specifies the position of the attribute (if the attribute happens to be a vector, or matrix) whose value will change.

Example: Changing the HMM's initial state probability vector (PI).

Events=
event = event( TIME )
condition = ( TRUE )
action = 
{    
    float new_PI[2];
    ...
    new_PI[0] = 0.5;
    new_PI[1] = 0.5;
    ...
    /* Changing PI values */
    mtk_set( new_PI[0], Predictor, "pi", 0 );
    mtk_set( new_PI[1], Predictor, "pi", 1 );
    ...
};
